Being Harry Potter

My six-year-old is reading the Harry Potter series right now. He finished book 2 today, and started book 3 tonight. He came out of his room with his book and a flashlight about an hour and a half past bedtime, and told my wife that as he reads the book, he sometimes feels like he's Harry Potter, and sometimes like he's in the story. My wife told him that that was one of the cool things about reading - you start to feel like you're in the stories.
